OIL-BURNER.

Specification of Letters Patent.

Application filed, October 21, 1909. Serial No. 523,750.

To all whom it may concern:

Be it known that I, HENRY L. ALBEE, a citizen of the Uni-ted States, and a resident of East Dou las, in the county of \Vorcester and State of Massachusetts, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

This invention relates to a burner of a type adapted to spray a suitable combustible oil, such as kerosene, and finely atomize itand mix'it with a suitable quantity of air before supplying it to the burning nozzle.

An object of this invention is to provide an oil burner with means for spraying a stream of oil and mixing it with a preliminary supply of air, and with means for further disintegrating or atomizing the oil and mixing it with an auxiliary supply of am Another object of this invention is to provide a burner with means for spraying an oil into an air chamber in the shape of a cone.

A further object: of this invention is to provide an oil burner with certain improvements at the outlet thereof, whereby advantageous results are obtained; and a still further object is to provide a device which will be simple in construction, strong and durable, and efiicient and noiseless in its operation.

These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompany. ing drawingsforming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side view, in elevation, of my device; Fig. 2 is a verticallongitudinal section through the center of the same; Fig.

3 is an exterior view of the oil feeder; Fig.

. 4 is an end View of the cap for the oil feeder;

Fig. 5 is a diagrammatic illustration of the screen aga1nst whlch the ml 15 sprayed; Fig. 6 1s a transverse section on the line 6-6 of 'Fig. 3; and Fig. 7 is a side view of the nipscre\\wthreaded connection 2, a member 3.

The member 3 may be made of one integral easting, but is shown in the form of two parts 4 and 5, connected together by means of a. screw-threaded connection 6. The forward part 4 of the member3 forms anozzle. The rear of the member 3 is provided with a screw-threaded opening, throu h which extends an oil feeder 7, and which 1s secured thereto by means. of corresponding screwthreads.

The oil feeder 7 is provided with a longitudinal opening 8, through which a supply of suitable oil, is adapted to pass'from a suitable source, not shown. Within the feeder 7, near the front end thereof and secured in the opening 8 in any well known manner, as by means of a screw-threaded connection 9, there is provided a-nipple 10, I

which is of a form well adapted to spray the oil in a finely-divided conical form. In

order to do this, this nipple 10 is provided ing from the opening 13 toward the front of' the member 3. This spray cone is formed in an enlarged cavity 14 formed in the front part of the feeder 7. This cavity 14 is provided with a plurality of openings 15, which form communicating passages bet-ween the air inlet 1 and the interior of the cavity 14.

Secured to the front end of the feeder 7 by a screw-threaded connection, there is provided a cap 16, which has a central 0 ening 17 therein. The cap 16 is adapte to secure between its inner face and the outer end of the feeder 7 a suitable atomizing screen 18. This screen 18 'is for the purpose of further atomizing and dividing the oil which has been mixed with a small quantity of air in the cavity 14, before it enters into a cavity 19 formed in the forward part of the member 3. The cavity 19 in the front end of the member 3 is choked by means of an annular flange 20, which extends induce a smoother-running burner and more eflicient results.

' of this outlet, to ether with the openings The operation of the device will be readily understood from the above description. The supply of oil is admitted from a suitablesource (not shown) through a valve (not shown),"into the inlet opening 8; The oil under pressure passes out through the opening 13 in the-nipple 10, and by reason of the fact the line of travel of each molecule of oil extends at'an angle to the line of travel .of every other molecule, and therefore the molecules "are not guided to travel in a straightforward'line, the oil will spray out intoa diverging cone, which will readily mix with the air let in from a suitable source by a valve (not shown) in the inlet pipe 1 and bythe openings 15. This partial mixture will pass through the screen 18, which further disintegrates and atomizes it, and from whence it travels into the cavity 19, where it. further mixes with a fresh supply of air, which is let in from the supply pipe 1 through the channel surrounding the feeder 7. The finely atomized oil, mixed with air, passes out through the outlet of the member 3. The choked nature 21, has been foun in actual practice to give smoother and more efficient results than can be obtained with burners working under the same conditions without these improvements.

Having thus described my invention, I claim as new and desire to secure by Letters Patent f i 1. In an oil burner, the combination with a feeder, comprising va member having a cavity therein with openings in the wall of said cavity, a nipple secured to said mem-i her and having a conical cavity converging to an ejecting opening, a cap secured to said member, and a screen interposed be tween said cap and said member, of a nozzle connected to said feeder and comprisin a body portion having a mixing cham er therein, an annular flange extending inwardly from the sides of said body portion,

forming a choke bore for said body portion, said body portion having angularlyv disposed openings therein, adjacent to said flange, and means forsupplying air to said nozzle.

2. In a burner, the combination with a esaeee nozzle, comprising a body portion having a mixing chamber therein, and an inlet flange communicating with the interior of said air supplying means, an open cap, connected to said member at theend ofsaidlast-named mixing chamber, an atomizing screen secured to said member by said cap, and a nipple extending/into said last-named mixing chamber and secured to said member, said nipple having'a cylindrical bore converging to a' conical cavity and having an opening at the apex of said cavity. 3. In a burner, the combination with a nozzle having a choke bore with openings at the side of said bore, ofameans for sup-' plying air to said nozzle, and means for supplying a mixture of air and oil to said nozzle, comprising a nipple, means for supplying oil to said nipple, said oil supplying means having a mixing chamber surround ing said nipple, and a screen atomizer disposed in front of said nipple.

4. The combination with an oil feeder, having an opening therein, of a screen ex tending transversely in front of said open-.

ing, and a nipple adapted to project a combustible fluid against said screen, said nipple having a cavity converging to an opening.

5.- Ina burner, the combination with a nozzle having a choke bore with openings at the side of said bore, of means for supplying air to said nozzle, and means for sup plying a mixture of air and a combustible fluid to said nozzle, comprising a feeder and a nipple connected to said feeder, said nipple having a cavity converging to an opening. a

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I
